Title:
SPRING DAMPER AND ACCELERATOR PEDAL USING THE SPRING DAMPER
Document Type and Number:
Japanese Patent JP2017002932
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a spring damper which prevents the generation of noise caused by a collision of a spring wire.SOLUTION: A spring damper 35 possessed by an accelerator device is arranged inside a hysteresis spring 49 possessed by a hysteresis mechanism part. The spring damper 35b is formed of a main body part 36 having an outside diameter D36 which is smaller than inside diameter Di49 of spring wires 493 of the hysteresis spring 49 which is arranged at an inner wall 102 of a housing 10 and at a lock part 431 so as to be capable of abutting thereon, and an outside protrusion 37 which is formed outside the main body part 36 in a radial direction, and has a tip 371 which is located outside the radial direction rather than a cylindrical virtual face VP49 which passes centers of the spring wires 493. When the hysteresis spring 49 is compressed by the pedal-in of an accelerator pedal by a driver, the outside protrusion 37 which is located between the adjacent spring wires 493 prevents that the spring wires 493 collide with each other.SELECTED DRAWING: Figure 4
